The locating ring is lapped on the locating step, and the drop-proof ring is lapped on the locating ring, so that the upper ends of the inner plug and the bottle mouth structure are limited, and the inner plug and the bottle mouth structure cannot be pressed into the bottle. The hanging table of the inner plug is provided with a clamping groove, when the bottle opening structure is installed, the bottle opening clamping hook of the bottle opening structure is clamped with the clamping groove on the hanging table, so that the bottle opening structure can not move towards the outside of the bottle any more, and the lower end of the bottle opening structure is limited. When the bottle mouth clamping hook is clamped with the hanging table, the hanging table is extruded for a certain angle, the outer side of the hanging table extends out of the neck section of the container mouth, the hanging table cannot enter the neck section, and the lower end of the inner plug is limited. Because the upper end and the lower end of the inner plug and the bottleneck structure are limited, the inner plug and the bottleneck structure are reliably connected with the container mouth and cannot be separated from or pressed into the container mouth.
As a preferable scheme of the invention, a plurality of sealing rings are arranged on the ring surface of the inner plug, and the sealing rings can be tightly attached to the inner wall of the container mouth part so as to prevent liquid from leaking out of the container mouth part.

Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
As shown in fig. 1-3, the anti-counterfeiting bottle cap of the embodiment is used for a white spirit bottle and comprises an inner plug 2 for being plugged into a container opening 1 of the white spirit bottle, a bottle opening structure 3 is sleeved in the inner plug 2, a bottle opening clamping hook 31 is arranged at the lower end of the bottle opening structure 3, a plurality of hanging tables 21 are arranged at the lower end of the inner plug 2, the bottle opening clamping hook 31 is clamped with the hanging tables 21, a positioning ring 22 is arranged at the upper end of the inner plug 2, a positioning step 11 is arranged in the container opening 1, the positioning ring 22 is lapped on the positioning step 11, an anti-falling ring 32 is arranged at the upper end of the bottle opening structure 3, the anti-falling ring 32 is lapped on the positioning ring 22, an inner cover 4 is connected with the inner thread of the bottle opening structure 3, an anti-counterfeiting outer cover 5 is sleeved on the inner cover 4, and the anti-counterfeiting outer cover 5 is connected with the bottle opening structure 3.
As shown in fig. 6, the container finish 1 is provided with a neck section, and in order to reliably connect the present invention to the container finish 1, the present invention must be limited on both the upper and lower sides of the neck section. The positioning ring 22 is lapped on the positioning step 11, and the anti-drop ring 32 is lapped on the positioning ring 22, so that the upper ends of the inner plug 2 and the bottle opening structure 3 are limited, and the inner plug 2 and the bottle opening structure 3 cannot be pressed into the bottle. The hanging table 21 of the inner plug 2 is provided with a clamping groove 431, when the bottle opening structure 3 is installed, the bottle opening clamping hook 31 of the bottle opening structure 3 is clamped with the clamping groove 431 on the hanging table 21, so that the bottle opening structure 3 can not move to the outside of the bottle any more, and the lower end of the bottle opening structure 3 is limited. When the bottle mouth hook 31 is engaged with the hanging table 21, the hanging table 21 is squeezed open by a certain angle, the outer side of the hanging table 21 extends out of the neck section of the container mouth 1, the hanging table 21 cannot enter the neck section, and the lower end of the inner plug 2 is limited. Because the upper end and the lower end of the inner plug 2 and the bottleneck structure 3 are limited, the inner plug 2 and the bottleneck structure 3 are reliably connected with the container mouth 1 and cannot be separated from or pressed into the container mouth 1. The ring surface of the inner plug 2 is provided with a plurality of sealing rings 23, and the sealing rings 23 can be tightly attached to the inner wall of the container mouth 1, so that liquid is prevented from leaking from the sealing rings.
When the anti-counterfeiting outer cap 5 is removed and the inner cap 4 is selected, the bottle is tilted, and the liquid flows into the bottle opening structure 3 and then flows out of the inner wall of the bottle opening structure 3.
Specifically, as shown in fig. 4 and fig. 7, the anti-counterfeit outer cap 5 includes a collar 51, an outer cap hook 511 is disposed in the collar 51, a bottleneck snap ring 33 is disposed at the upper end of the bottleneck structure 3, the bottleneck snap ring 33 is buckled with the outer cap hook 511, a cap body 53 is connected in the collar 51 through a plurality of connecting rods 52, and the cap body 53 is sleeved on the inner cap 4. The collar 51 cannot be removed because the bottleneck snap ring 33 is snapped with the outer cap snap hook 511 on the collar 51. When the cover 53 is pulled out or screwed, the connection rod 52 is disconnected from the cover 53, and the cover 53 is opened. Since the cover 53 is taken out and cannot be connected with the connecting rod 52, the anti-counterfeiting outer cover 5 plays a role in anti-counterfeiting, and the situation that the bottle is artificially adulterated is avoided.
In order to achieve the purpose of preventing splash when pouring out liquid, as shown in fig. 6,7 and 11, the top surface of the bottle mouth structure 3 is lower than the top surface of the collar 51, a splash-proof step 12 is arranged in the container mouth part 1, and the top surface of the splash-proof step 12 is not lower than the top surface of the collar 51. When pouring out the liquid, the liquid flows from the top surface of the finish 3 to the surface of the collar 51, and flows to the splash guard 12 of the container finish 1, and then flows out from the outer edge of the container finish 1. Because the top surface of the bottle mouth structure 3 is lower than the top surface of the lantern ring 51, the top surface of the splash-proof step 12 is not lower than the top surface of the lantern ring 51, and liquid always flows along the inner walls of the structures, and the situation that the liquid is directly poured out from the end part of the bottle mouth structure 3 is avoided, so that liquid is prevented from splashing. For the container mouth 1 with a sharp mouth, the liquid flows out from the sharp mouth part along the inner wall of the container mouth 1, so that the liquid is prevented from splashing.
In order to avoid the rotation of the cover 53, as shown in fig. 4 and 5, the positioning ring 22 of the inner plug 2 is provided with an inner plug inner anti-rotation rib 24, and the outer wall of the collar 51 is provided with a collar anti-rotation rib 512, and the inner plug inner anti-rotation rib 24 is engaged with the collar anti-rotation rib 512.
